Then the image should be at least 2550 pixels in width and 3300 pixels tall with a resolution of 300 PPI. Above all, raster images can’t be scaled to a larger size and if they are scaled, it loses quality and becomes blurry because the entire pixels become larger but they can be scaled down. For most images, this value is a visible color, but other measurements are possible, even numeric codes for qualitative categories.

Many web browsers now have some support for rendering SVG data but full implementations of the standard are still comparatively rare. If a dataset stored in one vector file format is converted to another file format that supports all the primitive objects used in that particular image, then the conversion can be lossless. Though it’s possible to make a vector resemble a photograph, the minute nuances of blended colors, shading, shadows, and gradient make it impossible to get a true-to-life representation of a photograph with vectors. Even if it were possible, the process would be excruciatingly tedious, as every color change would require a new shape to be created.

Compatibility is always a concern when you are working with different file types, but when it comes to graphics and images the type of computer graphic format you use is essential to how the image renders. Since raster images are pixel based, they are resolution dependent. raster and vector graphics difference The number of pixels that make up an image as well as how many of those pixels are displayed per inch, both determine the quality of an image. As you may have guessed, the more pixels in the image and the higher the resolution is, the higher quality the image will be.

It’s important to understand the fine differences between them and when to work with each—no matter if you’re a new designer, a seasoned pro or a marketer looking to hire a designer. Images whether it is raster or vector, both have their unique qualities and purposes. But it is important to know when you should choose raster and vice versa. Raster images are best for photos and vectors are best for logos, illustrations, engravings, etchings, artworks, etc. When you are detecting resolution in any output device, what do you think is that the files own eternal specifications? Imagine that you are going to print a brochure that needs a background image including size of 8.5” ×11” inch.

Raster vs Vector Graphics – Application:

Anything less, and quality will be sacrificed, as raster images cannot be scaled to larger sizes. When they are scaled, quality is lost and they become blurry, as each pixel becomes larger or photo editing software attempts to compromise by adding in colored pixels. Encapsulated PostScript files (.eps) are self-contained files that are the same mathematically as vector files, though they can be created from raster images as well. The format is one of the most compatible and portable because they are supported by almost all graphics software.

You typically don’t see the individual pixels unless the resolution is poor, or unless you zoom in on a raster image. Zooming in to isolate individual pixels gives you the ability to edit images with a high level of precision using a tool like Adobe Photoshop. Simply erase or change the color of individual pixels until you achieve the effect you’re looking for. Ever notice that as you zoom into an image, the quality gets lower? They are usually in the formats JPG (lossy), GIF (lossless), PNG (my favorite; lossless), and many others.

These are basically known as computer images constructed utilising a series of commands or mathematical statements that put lines and shapes in a two-dimensional or three-dimensional area or space. If you want to create an image with intricate details mimicking natural textures like a digital painting choose Raster. Finally, remember that you can always turn a vector graphic into a raster file with ease.

The ease vectors offer in terms of being resized without losing quality is incomparable to raster images being scaled up or down. Vectors are also ideal for when you want to store a large number of files without compromising on your storage space. Converting a raster image to vector involves recreating the image completely, and this can get complicated. Raster and vector are fundamentally different image formats, and getting them to look alike simply will not work most of the time. Because raster images can contain more complex detail and photorealism than vector images, data will inevitably be left out when you are transitioning from a complex format to a simple one. You will have better results when the source raster image is already made up of simple lines and color.

Still testing the waters in all the niches that graphic design encompasses? Then this post should help you get that first bit of second-guessing out of the way. We’d like to take you on a https://deveducation.com/ beyond-surface-level journey into the subject. When all is said and done, you’ll be able to effortlessly identify exactly when to use vector vs raster, based on your project’s ground plan.

  • With so many images to choose from online, it can be overwhelming to determine which file formats to begin with.
  • The most common way to do this is a row-major format, in which the cells along the first (usually top) row are listed left to right, followed immediately by those of the second row, and so on.
  • Because the format can support a wide range of colours and depict subtle graduated tones, it is well suited for displaying continuous-tone images such as photographs or shaded drawings, along with other detailed images.
